Patent GB-1435926-A (GB)
Title: Data processors
IPC: G06V10/75
Filed: 1973-07-05
Abstract: 1435926 Data processors INTERNATIONAL BUSINESS MACHINES CORP 5 July 1973 [17 July 1972] 32161/73 Heading G4A A programme store PSM is normally sequentially addressed by an address register PAR, a particular type of instruction (called condition branch) CB causes a branch address to be placed in a register BAR and a status register 600 to be set, and if a predetermined condition is detected during the execution of other instructions subsequent to the CB instruction, the branch address is transferred from BAR to PAR. In a programme for on-line character recognition, branches may be taken if a term of a logical expression, defining a particular character, is found to be zero. The particular condition which causes a branch may be selected from a set by an instruction, and detection of the selected condition causes a further status register to be set provided the condition branch register is still set. Certain instructions partially inhibit the condition branch status, while others re-enable it so that masking and unmasking of a CB instruction can take place any number of times, e.g. to prevent branching at different parenthetical levels of a logical expression to that existing on occurence of the CB instruction. Further instructions, by resetting the CB status register, terminate the effect of a CB instruction. An incrementable register BLR also provides return linkages for sub-routines. Address index unit IU is arranged to add the inputs supplied via gates 241, 242 and operates with a variable modulus which is determined by a set indexing status instruction. The modulus is set to determine the size of one or more selectable portions of data storage in DSM and provides address wrap-around in ranges of 256 or 512 locations. Execution unit includes a stack storage module SSM which is addressable sequentially by SAR and a data storage module DSM addressable by DAR. TOP and BOT address registers hold the address of the location adjacent that which last received or read-out a byte and allow the full/empty status of DSM to be determined. The logic operation performed by LU is specified by the instructions and the result is entered in a first result register RR1. Vote or count operations on a series of operands are performed as follows: RR3 is set with 1's which occur at corresponding positions in RR2 and the output of LU; RR2 is set with 1's which occur at corresponding positions in RR1 and the output of LU; and RR1 is set with the output of LU. Coincident 1's appearing in 1, 2 and 3 successive operands are then to be found in RR1, RR2 and RR3 respectively. Endaround shift of 1, 2 or 4 places in either direction and mixing of portions of different operands may also be performed in the registers RR. The contents of RR1 can be gated to any one of registers EXR selected by an instruction. The contents of all three registers RR can be selectively gated to data input register DIR as can the contents of a video buffer register VR.

Abstract: 1,048,260. Rolling. SMERALOVY ZAVODY NARODNI PODNIK. Aug. 15, 1963 [Aug. 21, 1962], No. 32242/63. Heading B3M. A solid of revolution 17 is transversely rolled between tools 12 and 13 attached to the peripheries of cylinders 14 and 15 rotating in the same direction. A typical tool is indicated as a development in Fig. 1 (not shown), the width of the tool increasing as rolling progresses until the transverse profile of the tool (Fig. 3, not shown), approaches that of the workpiece. Reduction surfaces 3 and 4 initially shape a workpiece while calibration surfaces 8 and 9 ensure that an accurate profile is produced. When the work is fully formed, blades 18 shear it from the stock 16. In place of the two halves of the tool shown, only one half may be used, and the helical reduction surfaces 3 and 4 may be roughened by knurling or sandblasting to achieve sufficient friction during rolling. The tools can be provided on planar rather than cylindrical surfaces.

Abstract: 732,647. Microscopes. OPTISCHE WERKE C. REICHERT AKT.-GES. Nov. 27, 1953 [Dec. 9, 1952], No. 32961/53. Class 97 (1). The travel on the coarse focusing adjustment is limited by a fixed stop r striking, approximately at the correct focusing position, an adjustable stop p which is positioned according to the thickness of the slide, by a gauge member n or z. The coarse adjustment has rack h and pinion g and the fine adjustment rack k and pinion j. In the modification shown in Fig. 1 the slide t is gauged between members land n and the stop simultaneously positioned by actuating the fine adjustment. The slide t is then placed on the stage, which may be lowered by the coarse adjustment to facilitate this operation and which may then be raised to a position determined by the position of the adjustable stop p and the fixed stop r, both of which are prearranged, or the fixed members l, n may be prearranged, so that the correct focusing distance between the object n and the objective e obtains. In the modification shown in Fig. 3 the slide t is gauged between l and n by actuating the coarse adjustment. The member n comprises a leaf spring s, a brake jaw y and a feeler pin v. When the slide is removed from the gauge the feeler pin v springs up and the brake jaw y clamps the adjustable stop p at a position in which it is in contact with the fixed stop r. In the modification shown in Fig. 7 the gauging operation is independent of both adjustments and the end a<SP>1</SP> of the lever z is set by inserting the slide t under the first roller in the direction R. As the arm el is raised and, on removal of the slide, lowered, the adjustable stop p is unclamped, adjusted to the height of the end a<SP>1</SP>, and reclamped. The height to which the stage is raised by actuating the coarse adjustment is limited by the fixed stop r striking the lower end of the adjustable stop p. The invention may be applied to microscopes in which the tube is adjustable.
